hangul is not an alphabet of arbitrary signs. each consonant shape mirrors the position of the tongue, teeth, or throat during articulation. each vowel is constructed from three cosmological elements: a dot for heaven, a horizontal line for earth, a vertical line for the human standing between them.

when consonants and vowels combine, they form syllable blocks -- compact geometric compositions where each component finds its precise position. this combinatorial logic makes hangul one of the most systematic writing systems ever devised.
